BT-113 should be used when advance payments, deposits, or partial payments have been made before invoicing. This includes down payments for orders, security deposits, or installment payments for services or goods. ### How does BT-113 affect the amount due for payment? BT-113 reduces the amount due for payment. The formula is: BT-115 (Amount due) = BT-112 (Invoice total with VAT) - BT-113 (Paid amount) + BT-114 (Rounding amount). If BT-113 equals BT-112, the amount due becomes zero. ### What currency should be used for BT-113? BT-113 must be expressed in the same currency as specified in BT-5 (Invoice currency code). The currency cannot differ from the invoice currency. ### Can BT-113 exceed the invoice total amount? While technically possible, BT-113 should not normally exceed BT-112 (Invoice total with VAT). If it does, BT-115 (Amount due) becomes negative, indicating the customer has overpaid and may be entitled to a refund. ### How are advance payments documented in German business practice? In German business practice, advance payments are typically documented through separate advance payment invoices (Abschlagsrechnungen) or payment confirmations. These documents should be referenced when using BT-113, and the VAT treatment must comply with German tax regulations. ### What validation rules apply to BT-113? BT-113 must follow BR-DEC-16 (maximum 2 decimal places), BR-CO-16 (proper calculation with BT-115), and BR-2 (non-negative values). The amount must be mathematically consistent with the payment calculation formula. ## Official sources and tools - [KoSIT Validator](https://erechnungsvalidator.service-bw.de/) - [Invoice Converter](/pdf-to-xrechnung) - [XRechnung Standard](https://xeinkauf.de/xrechnung/) - [Test Suite](https://github.com/itplr-kosit/xrechnung-testsuite)
